Pasadena, CA – By analyzing the distinctive cracks lining the icy face of Europa, NASA scientists found evidence that this moon of Jupiter likely spun around a tilted axis at some point.
Europa’s tilt could influence calculations of how much of the moon’s history is recorded in its frozen shell, how much heat is generated by tides in its ocean, and even how long the ocean has been liquid.
Greenbelt, MD – Over the last hundred years, the human population has exploded from about 1.5 billion to more than seven billion, driving an ever-increasing demand for resources.
To satisfy civilization’s appetite, communities have expanded recycling efforts while mine operators must explore forbidding frontiers to seek out new deposits, opening mines miles underground or even at the bottom of the ocean.

Pasadena, CA – An image from NASA’s Mars Reconnaissance Orbiter released shows NASA’s Curiosity Mars rover and the wheel tracks from its landing site to the “Glenelg” area where the rover worked for the first half of 2013.
The orbiter’s High Resolution Imaging Science Experiment (HiRISE) camera captured the scene on June 27th, 2013, with the orbiter rolled for an eastward-looking angle rather than straight downward. The afternoon sun illuminated the scene from the western sky, so the lighting was nearly behind the camera. This geometry hides shadows and reveals subtle color variations.
Pasadena, CA – The true identity of centaurs, the small celestial bodies orbiting the sun between Jupiter and Neptune, is one of the enduring mysteries of astrophysics. Are they asteroids or comets? A new study of observations from NASA’s Wide-field Infrared Survey Explorer (WISE) finds most centaurs are comets.
Until now, astronomers were not certain whether centaurs are asteroids flung out from the inner solar system or comets traveling in toward the sun from afar. Because of their dual nature, they take their name from the creature in Greek mythology whose head and torso are human and legs are those of a horse.

Moffett Field, CA – Scientists found treasure when they studied a meteorite that was recovered April 22nd, 2012 at Sutter’s Mill, the gold discovery site that led to the 1849 California Gold Rush. Detection of the falling meteorites by Doppler weather radar allowed for rapid recovery so that scientists could study for the first time a primitive meteorite with little exposure to the elements, providing the most pristine look yet at the surface of primitive asteroids.
An international team of 70 researchers reported in an issue of “Science” that this meteorite was classified as a Carbonaceous-Mighei or CM-type carbonaceous chondrite and that they were able to identify for the first time the source region of these meteorites.

NASA’s Wide-field Infrared Survey Explorer (WISE) images reveals hundreds of extreme Galaxies as well as millions of Supermassive Black Holes
Written by Whitney Clavin
Pasadena, CA – NASA’s Wide-field Infrared Survey Explorer (WISE) mission has led to a bonanza of newfound supermassive black holes and extreme galaxies called hot DOGs, or dust-obscured galaxies.
Images from the telescope have revealed millions of dusty black hole candidates across the universe and about 1,000 even dustier objects thought to be among the brightest galaxies ever found. These powerful galaxies, which burn brightly with infrared light, are nicknamed hot DOGs.

Pasadena, CA – Asteroid 2011 AG5 has been receiving a lot of attention lately because of a very unlikely scenario which would place it on an Earth-interception course 28 years from now. Here is a scientific reality check of this relatively nondescript space rock which is currently ranked a “1″ on the 1 to 10 Torino Impact Hazard Scale
As of February 26th, 2012, asteroid 2011 AG5 is one of 8,744 near-Earth objects that have been discovered. It is approximately 460 feet (140 meters) in size and its orbit carries it as far out as beyond Mars’ orbit and as close to the sun as halfway between Earth and Venus. It was discovered on January 8th, 2011, by astronomers using a 60-inch Cassegrain reflector telescope located at the summit of Mount Lemmon in the Catalina Mountains north of Tucson, Arizona.
